SHINGLE OR SHAKE MACHINE.

SPECIFICATION forming part of Letters Patent No. 445,742., dated February 3, 1891. Application filed. July 25,1890. Serial No. 359,930. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES W. BABCOCK, a citizen of the United States, residing at Crescent City, Del Norte county, State of California, have invented an Improvement in Shingle or Shake Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the general class of shake or shingle cutting machines; and it consists in the novel constructions, combinations, and arrangement hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to provide a machine for operating upon two bolts, one on each side of the machine.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a plan of my machine. Fig. 2 is an enlarged perspective view showing thedogs and connections by which the bolt is held in the carriage.

A is the frame of the machine. In one end thereof is mounted horizontally the driveshaft B, havingthe drive-pulley b, by which rotation is imparted to said shaft by means of a suitable belt.

On each end of the drive-shaft B is carried a sheave or pulley C, over which the endless band-saws D pass, one saw being on each side of the frame. In the other end of the frame are mounted the separate or independent shafts E, each carrying a sheave or pulley F on its outer end, over which said sheaves or pulleys the saws pass. These shafts are mounted in sliding boxes G and are adapted to be independently and separately adjusted by means of screws g, connected with them through the intervention of strong springs g, whereby the pulleys or sheaves are adapted to yield separately or independently if the saw should strike a knot in the bolt or there should be other extraneous and sudden resistance. The obj ectin having the independently adjustable sheaves F is to enable either sheave or pulley to be separately adjusted to accommodate the length of the particular saw passing over it, thereby afiording an op frame is mounted a vertical shaft K, upon the top of which is the feed-cam L, said cam consisting of a plate or disk having its upper surface cut out, asshown, with a regular curved flange near one half of its rim and a curved flange tending centrally at the other half of it. From each carriage extends inwardly a link M, having a downwardly-extending end 011, with an anti-friction roller m. This roller fits within the flange of the feed-cam and impinges upon it. N are parallel guide-bars extending across the top of the feed-cam on each side of the links, whereby they are held to their position and engagement With the cam. A rotary motion is imparted to the cam by means of a pulley O on the shaft K and a belt 0, extending to a pulley p on a vertical counter-shaft P, which carries a worm-gear p, with which said geara worm b on the driveshaftengages. Now it will be seen that by rotating the feed-wheel one of the carriages is drawn inwardly by means of the engagement of its link with the centrally-tending portion of the cam-flange, while the other carriage, whose link engages the outer or regular curved portion of the flange, is allowed to be drawn back fully by means of a weight WV, connected by a cord to with its outer end. WVhen the bolt of the inwardly-working carriage is operated upon so as to cut a shake therefrom, said carriage is relieved by the cam, and its weight pulls it baolgwhile the cam now feeds the other carriage forward so as to cut ashake from its bolt. Thus a shake is cutfrom a bolt on each side alternately.

In order to throw the mechanism into and out of gear, as desired, I have the tightenerpulley Q operating against the belt, said tightmade Vertically adjustable in order to regulate the thickness of the shake.

The bolt is held in the carriage by means of a'fixed toothed dog S on one side and a pivoted toothed dog S on the other side. This'pivoted-dog has afiange s on its outer side, which operates against the-vertical side of the carriage-track h, and thereby holdsthe clutch inwardly against the bolt. The vertical side of the carriage-track near the return limit of the carriage is cut away at t'and-pro-- The vided with a projecting cam-flange t. flange s of the pivoted dog when it comesv to this portion drops into the openingand gets behind the projecting end of the-flange 15,

whereby the dog is withdrawn fromthebolt,

therebyenabling it to be readily removedand readjusted.

In the frame are madetheinclined; chutes a, converging downwardly andadapted to re-* ceive and discharge the shingles or shakes; If desired, there may be; a pivoted toothed dog like S and devices to operate it on both sides of the bolt.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a shingle or shake machine, the combination of a pair of band-saws,one oneach side of the machine, andalternately-reciprocating bolt-carriages, one on each side, and-a" cam connection between the carriages, whereby the bolts are cut alternately, substantially as herein described.

2. In a shingle or shake machine, thecombination'of a pair of band-saws, oneon eachside of the machine, alternately-reciprocatingbolt-carriages, one on each side and adapted to alternately feed their bolts to the saws,- where by a shake is cut from each bolt alternately,

and a central feed mechanism comprising a cam and connections for operating the carriages, substantially'as herein described.

3. In a shingle or shake machine, the 00m bination of the band-saws, one on each side of the machine, the alternately-reciprocating bolt-carriages, one on each-side of the machine, and the means for alternately feedingsaid carriages, consisting of the central rotating cam and the links from saidcarriages engaging the cam, substantially as herein described.

4. In a shingle or shake machine, the"-combination of the band-saws, one on each side, the sliding carriages, one on each side, the

means for alternately reciprocating'the' carriages, consisting of therotating cam between them, the links from the carriages engaging the cam, and the weights for returning the carriages, substantially as herein described.

5; In a shingle or shake machine, the combination of the side saws, the sliding carriages, one for each saw, the central rotating cam, the links from the carriages engaging the cam, whereby said carriages are alternately fed, the weight for returning the carriages, and the transverse guide-bars for holding the links in place on the cam, substantially as herein described.

6. In a shingle or shake machine, the combination of the band-saws,one on each. side, the sliding.bolt-carriages, one for each saw, the central ,rotating cam, thelinks flTOliLtllG carriagesen gaging said cam, whereby the'carriages are alternately drawn inwardly, the weights-for returning the carriages, andthe means for rotating the cam, consistingofithe shaft on which it is mounted, the drive-"shaft and the intervening worm, worm-gear, pulleys, and belt, by which the powerof the driveshaft is transmitted to the cam shaft, sub

stantially as herein described.

placed cam and connections therefrolnfor operating the carriages alternately, the p ll-- leys ateach side of one end of themachine, the independently-adjnstable pulleys,uone at' eachside .of the other end of the machine, and

the endless-bandsawspassing over said pul leys, substantially as herein described.

. 8. In a shingle or shake machine,.the combination of the sliding'bolt-carriages,.one at each side of the machine, the central camand connections'theretroni for operatingatheca rriages alternately, the pulleys mounted at each side of one end of the machine, the pulleys mounted at each side of the otherendot' the machine, the independent shafts of said last-- sid e, ,the. alternately-reciprocating carriages, thecentral cam and engaging'links of the carriages, whereby the carriages are fed,

the power-transmitting belt for operating the cam, the sliding tightener-pulley affecting said belt, the lever, and the rope or cord connectingathe lever with the sliding tightenerpulley, substantially as herein described.

10. In a shingle or shake machine, the bolt of the pivoted toothed dog and swinging it to it from the bolt, substantially as herein de- 10 free it from the bolt, substantially as herein scribed.
